The radiators in my house have all been replaced over the last year or 2 and I'm wanting to balance them. My understanding is that first I should get the boiler flow/return temperature difference right with all the radiators full on, but I'm not sure what that difference should be. It's a Greenstar Ri, about 7 years old I think, I found a manual https://www.freeboilermanuals.com/worcester/ which gives heat output for '40/30', '50/30' and '80/60'. Does that mean I could set flow to 50 and return 30, for example? And if the difference is 20, should I also make that the difference on all the radiators to match when I balance them?
Thanks in advance for any help.
